Iv'IACHINE FOR MAKING METALLIC BBISTLE HOLDERS.

Original application filed-May 2a, 1916,

T0 all w hom may concern:

Be itknown that I, ARTHUR W. LE Bonnr,

a citizen ofthe United States, residing at Bridgeport, in-the county of .Fairlield and State of Connecticut, have invented a new holders for brushes.

. provide means whereby the 1 said bristle holders in: the shape of'metallic cups are formed from one or more wiresin an expeditious and convenient manner; to provide automatic mechanism for forming these cups comprising means for supplying the wire automatically, and means for drilling into the end of each of a plurality of wires. in regular order, preferably by a plurality of drilling operations, means whereby when. the tuft is placed in a cup thus formed, it

is temporarily secured thereinby an auto mat'ic'ally clinching operation, and means whereby the cup is then automatically cut off the wire so as to come'through the'rest of the operationsas a unitsepara'te from the wire; and, also, more specifically, to prof vide a rotary turret capable of operating on a plurality of wires provided with'means for rotating the wires carried thereby on their own axes at certain times during the operation of the said turret, so that thewire itself shall be projected through the.

turret into a certain position and rotated on its own axis while a forming tool shapes it to a convex' form at'the end, then indexed around and rotated while an oppositely rotating drill is forced into its end axially, then'fed around while still rotating, and its rotation continued during a second drilling operation, then fed around another step and Serial no. 99,100.

its rotation on its own axis arrested while the tuft of bristles is applied to it, and clinched in its end, the intermittent rotation of the. turret being then continued and the rotation of the wire on its own axis being then resumed while the convex end of the wire is forced inwardly to permanently secure the tuft therein, and the portion of the Wire constituting the cup with'a tuft of bristles.

The invention is illustrated in the form of a machine for making tooth brushes in which a base is provided for supporting a main frame of the machine which is shown as consistingof several parts 101, 102, 103, and 104. The motive power for the machine is preferably. obtained from a motor105 which drives a shaft 106. This shaft by means of a worm 107 and worm wheel 108 drives what I call the main shaft 109, running longitudinally of the machine.

As has been stated the tufts are formed by forcing bunches of bristles into metallic cups, and these cups are made on this machine. For this purpose wires A, preferably of aluminum, are supported on supporting reels 110, the end one of which is rotatably carried by a frame 111 supported in any desired way, as for example, by a post 112 extending up from the floor. The details of this reel willnot be described as they do not constitute a part ofthis invention.

Indexing turret for the wares.

These reels are located about a central shaft 113 and are adapted to support several wires while they are fed through a series of heads 011 a turret which is mounted on a hollow shaft 114 to which the shaft 113 is pivotally connected. This shaft is mounted on a turret frame 99 mounted on ways 115 on the frame member 102. The shaft 106 is provided with a gear 116 fixed thereon which meshes with a gear wheel 117 loose on a shaft 118 parallel with the shaft 106. Rotatable with this loose gear 117 is a hub 119. In the form shown the shaft 106, and also the gear 117, makes eighteen revolutions to one of the shaft 109. On thisshaft 109 is an indexing cam 121 which operates an indexing lever 122 provided with an adjustable and removable shoe 123 for engaging the cam and receiving its motion from it. This lever is provided at its other end with a second removable and adjustable shoe 125 which stops a pawl 126 that is piv- At thesame time a latch' 130 pivoted on the frame engages behind a tooth 132 on the clutch disc and positively prevents it from rotating backwards. The lever 122 and latch 130 are pivoted on a bracket 20 fixed on the frame member 102.

The rotation of the clutch disc 120 causes the rotation of the shaft 118 throughthe other clutch section 133'which is fixed on this shaft. 134 indicates an adjusting nut for disconnecting the clutch sections.

The operation is very simple. The gears 116 and 117 together with the hub 119 are rotating constantly, but inasmuch as the shoe holds the pawl 126 in the position shown in Fig. 5 this rotation of the hub 119 is idle while the shoe 123 is on the low part of the cam 121. When it passes off this part to the high part of the cam the shoe 125 is drawn out from under the pawl 126 on which the pawl 126 is pivoted to rotate with it. It willrotate as many times as the earn 121 provides for. In the present instance this cam is so designed as to give it nine complete rotations. Before the ninth inthe following way.

lVire feed.

The first operation, of course is to draw the wire into the head and that is performed On the shaft 109 is 141 which may be all in one piece, but is shown as having behind its short arm an arm 142 pivoted on the pivot stud onwhich the lever swings. Into this arm 142-extends a pin -143adapted to be operated by the oscillation of a collar 144 fix'ed'on a rod l'iavlng a head-on 1t for. manual manipula tion. This pin is normally pressed in by a spring 146 so that its end enters a socket in the short arm of the-lever 141 and-under normal conditions this lever operates-likeany other lever. The arm 142- necessarily works with the; lever under these conditions,

but in setting the machine up, lfe-lt is desired to disengage the lever 141 from 'th'e parts which it operates, th rod is oscillated to pull out'the pin 143 and then-the arm 142- and lever 141 can be operated independently and the former moved for adjustment or for hand feeding. This arm 142 is provided with a yoke 147 which receives trunnions- 148 on a collar 149 mounted on a feed lever rod 150. This rod is adapted to reciprocate in its hearing 151, and is reciprocated by the.

lars are of course rotatable with the turrets and the feed lever rod 150is provided with a radially projecting operating end 153 which can be moved by the. reciprocation and oscillation of this rod into a position to come between them as they come around into the proper position (Fig. 11.) The turret stops in such position each time that one of these double flanged collars is in engagement with the feed lever rod end153 and consequently is 'un'derthe' control of theare responsible forthis action. 1 155, having been drawn back tothe extreme same.

The. conical surfaces be tween the jaws 156 and an intermediate slid? ing member 161 (operated by the levers 157 The jaws end of the stroke, start forward immediately after the collar 158 is moved to theleft far. enough 'to release the ends of th'e clutch le.- i vers 157, and therefore the friction jaws move the wire forward to the-left inthis figure. It willbe understood that in; the position in which this operationhas been assumed to start the wire between the endl i of the clutch andthe screw step 162 has been removed by means to be described here inafter. Therefore the forward movement of the jaws 155 pushes the endof the wire up against this stop and they have sufficient. movement to make sure of accomplishing. this result, but as they grip the-wires frietionally only they may have an excess ofthat movement. As they stop moving fo r.-. ward the collar 158 moves again to the right andth'e wireis clutched positively in posi.-. tion by the jaws 156. I donot claim herein' the details of this clutch as it does notconstitut'e a part of this invention and any; equivalent can be used. Y 7

It is to be noted that the lever 159 is shown. in Fig. 9 as provided'with mechanism like that of the lever 141 forthe same purpose.-' hen the rod 145 is turned to withdraw the pin 143 it also withdraws a similar pin 14-3 and frees the collar 158.

The stop pin 162 is mounted on an arm 163 i which is adapted to swing on the center of a bolt 164'. '(Fig. It is normally held down by gravity against a pin 165 mounted on a stationary member. 166. Therefore if it is desired to take shortends of wire out of the jaws it is convenient to swing this stop up out of the way so that the wire can be pulled or pushed through.

by'a cam 180 on the shaft 109.

It is to be noted that the belt which operates these pulleys 174 extends around them in such a way as to engage them in all their positions except one, (see Fig. 9). The reason for this will appear later, but it will be obvious that in all other positions these pulleys, and consequently the wires which they control, are rotated constantly on their own axes independently of the indexing of the turret.

it 011.79 forming.

As the turret rotates away from the feed position as indicated in Fig. 22 the Wire moves downwardly to the position indicated in that figure as Form and drill. This is the lowest position and in that position the mechanism is designed in the present case to perform a shaping operation on the projecting end of the wire and to drill axially into it. This shaping mechanism is actuated (Fig. 13.) This cam by means of a lever 181 reciprocates a tool holder slide 182 movable in ways on a stationary member 183 on the turret frame 99. A spring 184 moves and normal- 1y holds the tool holder slide back from the work and the cam positively moves it upwardly to the right in Fig. 13. This slide:

is provided with a rest in the form of a surface 185 for a cutting tool 186. Extending in through the body of the slide are shown two screws 187 which are adapted to be adjusted to form surfaces for the tool to engage on that side. A binding screw 188 is shown for holding the tooldown on the surface 185 and an adjustingscrew 189 for controlling its adjustment longitudinally.

The reciprocation of this tool toward and from the Work as indicated in Fig. 13 is accomplished in this manner andthe tool is designed to out the blank A into-the form shown in Fig. 16 so as to reduce its neck and produce a convex circumferential projection aat its end. The wire A rotates on its axis.

DriZZin{ lVhile this operation is being performed the first drilling operation also takes place. On the shaft 109 is a drill cam 190 operating a lever 191 which moves a slide 192 on ways 193 on an adjustable table 194 located in ways on the frame 102. This slide is a drill head carrying two drill spindles 195 and 196 as shown in Figs. 18 to 21. Each of these spindles is provided with a pulley 197 On this shaft is another pulley 173 which is provided with a belt and these pulleys are constantly operated from the shaft 172 by a belt passing over thenrand over a pulley 198 on this shaft. The drilling operation isshown more especially inFig. 21 and in that case the drill carried by the first drill spindle 195 per-:

' The drill on the spindle 195 having performed its preliminary drilling operation the drill slide is withdrawn as the tool holder slide 182 is withdrawn and the turret is then indexed around one more position. i In the second position the blank which has previously been mentioned is brought to the position indicated by the word Drill in Fig. 1

22, and the operations repeated. In this case the second blank is formed anddrilled while the first blank receives its finish drilling operation from the drill carried by the spindle 196. This drill is a little bit longer and slightly larger than the first drill so thatit performs a finishing operation.

It will be understood, of course, that the successive blanks are operated upon in this way. I i will therefore trace only the first blank.

In this position the head of theturret which supports the blank is freed from the beltas indicated in Fig. 9 and does notrotate. is introduced longitudinally into the end of the blank while held in this position by means that is described in my above mentioned original patent. It is sufficient to say that it is pushed in positively and the pushing means drawn out. so as to leave the doubled over part of the bristles extending to the bottom of the hole drilled in the blank and projecting from the mouth thereof.

Nz'clcing. I On the shaft 109 is a nicking cam 200.

This operates a lever 201 shown in Fig. 24.

This lever is pivoted on thetable 194 and is provided with two arms, one of which is integral with the lower part of the lever as indicated in Fig. 24 andthe other arm These,

202 is pivoted on the saine pivot. arms are connected by. a spring pin 203 which forces them yieldingly apart as far as possible. The arm 202 is provided on its The next position of the turret. brings the blank into the position marked.

The tuft. of bristles B.

By rotating both the drill and V these elements. of this arm 202 inwardly and holds it in con end with-a. guide plate: 204 and with a bumper- 205 or othermeans for limitingits motion inwardly. In the present case this bumper is shown as spring-pressedand as engaging against the circumference of the temporarily stationary head 138 which is located in position to be operated'uponby This then limits the motion stant position.

l he arm 201 is provided with an ad ustable rod 206 pivotally connected withthe arm. At the end of this rod-are;pivoted two links 207, each one also pivoted to a *l'evefr 208. These levers are pivoted on pro- "jections 209 carried by the arm 202. Carried'by these-projections are guides 211 for reciprocating slides 212 which are "PIVOhed 'to the levers 208. These slides carry nicking'jaws 218. Each of these jaws is mounted on a pin holder 21 1- screw-threaded into the guide 212 and each one carries within it a I nicking pin-'215 headed inside and held in position in the nicking pin hold- These'are arranged to be loaxially transverse to the plane of the tuft of bristles sothat they will extend into the concave side of the bent overcenter thereof. The operation of these-nicking jaw's'is shown in Figs. 27 and I 28 especially and the results in Figs. '29 and 30,'the former two figures showing two different positions of the jaws, the positions in Figs. 24 and 27 being the same.

Swedgz'ng mechanism.

It will be noted that after the turret in- 'deXes,"when the 'nicking operation is completed, the head which has held the blank subjected to that operation will aga n come into rotation by its pulleyengagmg the belt. On the shaft 109 is a swed'ging cam 220 located in the. present instant-eat the end of theshaft beyond the frame (Figs. 3' and '34). This operates,=by a lever 221, an adjustable rod 222 and oscillates a shaft 223.

This shaft is provided'with a slabbe'd off end 224 which projects into a frame-225 carried by a bristle hopper frame 219 and engages the ends of two swedge roll carrier levers 226 pivoted on a stud227 carried by the same frame. "Springs 223 force these ends of the levers-against the end of the shaft 223 and it will'be obvious that by the oscillation of this shaft thelevers will be moved-alternately to the positions shown in Figs. 31 and 32.

While in the position shown in the former figure, the nicked cup with itstuft of bristles B thereinJcomes' up into position between th'e ends of the levers 226. In the present case one of these leversis shown as provided with two adjustable holders 229 eachca'rrying a 'swedging roll 230. The other lever, that is, the one below, carries a single roll 231 in the same way. These rolls are mounted tor'otate freely on bolts 232. When the shaft 223 turns to bring the parts intothe position shown in Figs. 32 and 33 the rotating blank A engages between the freely rotatableswedging rolls.

. They then operate upon'it to reduce it from the-form shown in Fig-'35 to that shown in Fig. -36. "The lower one of theserol-ls 231 -is shownas having a flange 233' thereon so as to give'a finished product. Thisoperation has the eflectof turning the convex circumferentialprojection a inwardly so as'toform an inwardly projecting collar'a in intimate contact-with the bristles of the tuft so that the same will be heldpermanently in the cup in-addition to the holdingaction of the I nicks a. ThlS'El'lSO'i provides a circular passage and consequently a'circular tuft. This is shown in Fig. 37. It will be noticedalso that this metallic cup which forms the-base of the bristle tuft-is shown 'hereas of uniform exterior diameter throughout its length and reduced fromthe fulldiameter of the aluminum wire blank.

Cutting 0 7f The next indexing of the turret brings this blank around tothe positionmarked Cut off and transfer in'Fig. 22. 'Referring now toFig. 13 it will'be "seen that the tool holder-slide 182 is connec'tedby aslot and bolt construction at-237 wit-ha lever 238 pivoted on the stationary-frame 99 in which the turret operates, and this is provided with a non-rotary'cutter239 havingasharp cutting edge and adapted to move in. toward the rotatingblank and cut it oif asindicated in Fig. 17. Itwvill be noted that the cutter itself is shown as provided with a concave edge whichacts to round off the end of the blank as itis-cut ofl and removed. The tuft is then received by-the transferring inechanisinwliich will not be described herein, as it is shown in my above mentioned original patent.

Operatz'tm.

The operationof the machine is as fol lowszA plurality of wires A, as stated, are located on the wire-carrying reel which' is capable of rotating in its supports with the cup forming turret. This turret isrotated intermittently, a step 'at a time, and one wire having been pushed forward through the first ch'uck or head is stoppedin a definite position and then clamped by the clutch. The turret then rotates one sixth "of i a *revoh'ition "and stops. The first drill is brought up --to "it so as to drill out a hole axially'into the'end of the wire.

a little larger and longer than the first one so that it finishes the opening and brings it to depth. It will be understood that the two drills always act simultaneously one on a new wire and the other on a wire which has been through the first step of the operation. The two drilling operations having been completed the head rotates a third step and the first mentioned blank is then brought up into position to receive a tuft of bristles which is supplied to it in a way which is described in said patent. It will be understood that the head isstopped here while the tuft is inserted in the cup and that the nicking or clinching jaws are operated to force the metal of the cup inwardly at two opposite sides to clinch the tuft in position. The belt which rotates the several heads with which the turret is provided is so arranged that it engages the pulleys of the several heads in all positions thereof except in this position and here it is free from the pulley and consequently the head does not rotate while the tuft is being applied to it nor during the nicking or clinching operation. After that is finished the. turret rotates another step bringing this pulley into contact with the belt again and the turret comes to a stop in the next position where the convex edge of the cup is forced inward to permanently clinch the cup with its tuft of bristles. Thezturret, ofcourse, stops while the cup is cut off and discharged from this part of the machine, but the head rotates on its own axis. A needle forces the tuft of bristles straight out into the metallic cup, which is'a-t that time in alignment with the needle, and leaves them in this cup. It is as this needle is withdrawn that the clinching or niclring operation takes place to force opposite metallic projections into the tuft and permanently secure the bristles in the cup.

The last operation before the cup is out off from the wire is to force inwardly the convex enlargement at the end of the cup to finish the cup and tuft and still leave the cup of uniform diameter outside.- In other words, the projection which formerly was outside is now located on the inside and the outside left in a true finished form. This projection on the inside grips the bristles and permanently holds them in position, the

nicking operation being mainly for temporarily holding the tuft in the cup.

When the completed tuft in its cup is just held by the head, a transferring device swings up into position to engage the bristles and prevent the tuft falling away and at the same time hold it on the transferring device. Thedetails of the operation of this transferrer will not be repeated here,

but it is sufficient to say that the transferrer having grasped the tuft beyond its metallic cap swings over through a considerable are into a substantially horizontal position from which the tuft is applied to the brush handle or blank under pressure and left secured therein by friction.

It will be seen therefore that this machine is entirely automatic, forming the wire into holding cups for the tufts, drilling the blanks and forcing the tuftsinto the holes thus formed so as to produce the complete tuft which needs only tohave the bristles trimmed down to the proper length after leaves the machine. All the parts are conveyed from one position to another in the machine automatically and there is no need for any expert oversight of the operations. Practically all that the operator has to do is to see that the machine is running, andto see that it is properly. supplied with the raw products which it uses. No claim is made herein to the process disclosed. The right is reserved to present the claims thereon in a divisional application.

Although I have illustrated and described only a single embodiment of the invention and shown it as applied to a definite character of brush tuft I am aware of the fact that many modifications can be made in the 'de-. tails of construction and combinations of parts of the mechanism and that it can be applied to the manufacture of other types of metallic holders without departing from the scope of the invention as expressed in the claims; Therefore,I do not wish to be limited in these respects, but what I do claim is I j 1 1.

In a brush making machine, the combination of a turret, means for intermittently rotating the turret, a plurality of heads on the turret, each having a chuck for holding a wire centrally therein, means for feeding a wire through each chuck when in one position, means for stopping the wire and limiting its position when the feeding operation is complete so that the wire will project beyond the end of the head and the end of the turret, means for shaping the end of the wire at the next position of the head, means for drilling a hole centrally into the end of the wire, means for completing the hole at the next position of the head for a tuft of bristles, means for then nicking the wire to force projections inwardly for the purpose of holding the tuft of bristles there in, means whereby at the next position the a wire centrally therein, a tool holder mounted on the machine, a forming tool carried by said tool holder for engaging the rotating wire carried by one of the heads and shaping it, a pivoted frame, a cutting tool mounted on said frame, and means whereby the motion of said forming tool into operative position will also move the cutting tool into a position to cut off the end of the wire held by another head.

6. In a metal working machine, the combination of a turret having a plurality of heads thereon, means for forming a wire held by one of the heads, means for simultaneously cutting off a wire held by another head, said two means comprising a slide, a forming tool holder carried by said slide, a lever carrying said cutting means, and a connection between the lever and. the slide whereby the movement of the slide to operative position also swings the lever to operative position.

7. In a metal working machine, the combination of means for holding a metallic wire, means for forming up the end of the wir to provide a projecting integral ring around the outer edge thereof, means for drilling centrally into the end of the wire to form a cup for receiving the bristles, means for shaping the cup to cause it to grip the bristles, and means for thereafter forcing the projecting ring inwardly to bring the exterior surface to a true cylindrical shape and form an inward projection for tightly holding the bristles.

In testimony whereof I have hereunto affixed my signature.
